QuestionMay 26, 2025

Though we know that the hippocampus plays a role in learning and memory, the mechanisms by which it works are still not fully understood. In one study, adult mice that ran on a wheel after having a particular experience were more likely to behave as if they had forgotten that experienc than were mice that had the same experience but didn't exercise afterward. The researchers believe that this forgetting was caused in part by neurogenesis in the hippocam pus. This finding may seem to contradict the findings of other studies which suggest that the development of new brain cells in the hippocampus is beneficial to the encoding of memories. But the researchers behind the mouse experiment address this apparent paradox by noting that degrading or remodeling existing memories may actually be a key part of learning, as it could free up the brain to store new information. What is the meaning of neurogenesis as used in the passage? the creation of neurons the specialization of neurons the deterioration of neurons the consolidation of neurons

Answer

the creation of neurons Explanation 1. Identify the context of neurogenesis Neurogenesis is mentioned in relation to the creation of new brain cells in the hippocampus. 2. Determine the meaning based on context The passage discusses neurogenesis as a process that involves creating new neurons, which may affect memory by remodeling existing memories.
